Chamber Installation Guide
Electrical power, condenser cooling water, humidity water, compressed air, LN2, and condensate drains may need to be connected to the machinery. Some equipment may require additional connections. Shakers may require some vacuum ductwork to be installed. Consult your specific manual for complete requirements. Your Thermotron Application Engineer will be happy to assist you with the specific requirements. Always refer to your local codes when making the utility connections.
Make sure the location you choose to place your equipment can handle the heat dissipation from chambers with integral air cooled condensers. As a general rule, an air-cooled cascade system can dissipate approximately 12,000 BTU/hour per compressor horsepower of the high stage system. An air cooled single stage system can dissipate approximately 15,000 BTU/hour per compressor horsepower.
For example, a SE-300-3-3 can dissipate as much as 36,000 BTUs per hour when running under full load conditions (3 horsepower x 12,000 BTU). These maximum heat loads only occur under full refrigeration load conditions when ramping down the chamber’s temperature as quickly as possible.
Most chambers need 36 inches of space around them to provide adequate room for servicing the equipment. Smaller chambers on casters can sometimes be placed in tighter spaces since they can be rolled out to allow for more room when needed. Always refer to your local codes when placing chambers.
Chambers should be placed in a temperature controlled room with adequate ventilation. Aircooled chambers require a high volume of air flow over their condensers. Placing a chamber too close to the wall may limit air flow. Depending on the model, chambers can operate with as little as a few inches of space behind them or up to a minimum of 12 to 15 inches of clearance is needed for others. The condenser relies on having an adequate supply of room temperature air in order for the chamber to perform its best. It is important to follow all local codes when placing your chamber.
Remote Refrigeration or Remote Air-Cooled Condenser
If the chamber has a remote refrigeration section or remote air-cooled condenser, determine where these components will be located. Is there unobstructed space for an interconnect route? Routing of refrigeration and electrical interconnect above drop ceilings and through an obstructed area typically increases installation costs and may decrease equipment efficiency. Generally, the shorter the interconnect, the more efficient the refrigeration system will be. Try to locate the equipment in an area with open access for interconnecting the components. Refer to local codes when placing the equipment.
Panel Walk-In Chambers
Building a Walk-In Panel Chamber in your facility may require some prep work. Facility floor quality is very important when installing a Panel Walk-In Chamber. The floor must be level to a standard of 1/8-inch per 10-feet or more in any direction. If the facility floor has high and low points, it will not properly support the chamber structure. It also makes it very difficult to assemble the structure squarely as it will attempt to flex to conform to the facility floor. This can possibly affect the chamber door and panels and their ability to completely seal and could possibly reduce the lifespan of the chamber.
